In the excerpt shown Thursday night, Obama also listed the United States' enemies for O'Reilly: "Al Qaeda, the Taliban, a whole host of networks that are bent on attacking America who have a distorted ideology who have perverted the faith of Islam and so we have to go after them."

In regards to a nuclear Iran, Obama said it would be "unacceptable for Iran to possess a nuclear weapon; it would be a game changer" and he assured both O'Reilly and the Fox News audience that he "would never take military action off the table."

Watch:

More excerpts from O'Reilly's interview with Obama will air next Monday, Tuesday, and Wednesday on "The O'Reilly Factor."
